1. Introduction
The Ex-Time 40 and the Ex-Time 50 are quartz movement wall clocks
designed for industrial application in areas with an increased risk of
explosion in zones 1 and 2, in accordance with directive 1999/92/EC
(ATEX 137).
2. Safety Advice
These Operating Instructions contain information and safety regulati-
ons which must be followed to ensure safe and reliable operation of
the unit under the described conditions. Failure to follow the informa-
tion and instructions contained in these Operating Instructions can
have dangerous consequences or may violate applicable rules and
regulations.
Please take the time to carefully read through these
Operating Instructions before you start using the unit.
In the event of any doubt or discrepancies (e.g. due to errors in trans-
lation and/or printing), the original German language version of the
Operating Instructions should be referred to.
3. Faults and Damage
If there is any reason to suspect that the safety or integrity of the unit
has been compromised, then it must be taken out of operation imme-
diately and removed from the Ex-zone without delay.
Precautionary measures must be taken in order to prevent any further
use of the unit in the Ex-zone. It is recommended that the unit should
be then sent to the manufacturer to be examined.
The safety and integrity of the unit may be compromised by,
for example:

14
- External damage is evident on the housing.
- The unit has been subjected to excessive loads for which it is not designed.
- Incorrect storage of the unit.
- Damage sustained in transit.
- Correct certification is illegible.
- Functionality errors occur.
- Permitted tolerances or threshold values have been exceeded.
4. Safety Regulations
Use of this unit assumes that the operator observes conventional safe-
ty regulations and has read the certificate in order to eliminate faulty
operation of the unit.
The following safety regulations must be complied with:
- The housing of the quartz mechanism and the battery
- compartment must not be opened within the Ex-zone.
- The battery must only be changed outside of the Ex-zone.
- Additional or spare batteries must not be carried in the Ex-zone.
- Only the "type-approved” batteries as listed in these Operating - -
- Instructions may be used.
- Ensure that Ex-Time 40 and 50 units are securely attached
- to the wall.
-
It must be ensured that the clock does not accidentally fall into zone 0.
- The clock should only be cleaned with a damp cloth.

7. Use and Application / Operating Instructions
Before use, please read these operating instructions very carefully
in order to familiarise yourself with the functions of the Ex-Time 40 /
Ex-Time 50. For you own safety and information, please read the follo-
wing instructions.
7.1 Commissioning
Use an appropriate screwdriver to undo the two screws on the battery
compartment cover (on the opposite side from the quartz mechanism).
Remove the battery compartment cover and insert a battery of the cor-
rect type (LR14) (refer to the table under section 6.1 – Table with type-
approved batteries ) into the battery compartment. Please refer to the
diagram on the housing to make sure that battery is inserted with the
correct polarity. Refit the battery compartment cover (the spring faces
towards the battery), refit the battery compartment cover screws and
tighten securely. Then use the white adjusting wheel on the housing of
the clockwork mechanism in order to set the correct time.
7.2 Changing the battery
To change the battery, use an appropriate screwdriver to undo the two
screws on the battery compartment cover. Remove the battery com-
partment cover and dispose of the old battery.
Insert a new battery (only use type-approved batteries ‘ refer to the
table under section 6.1 – Table with type-approved batteries; check for
correct polarity ‘ check the diagram on the battery housing ). Refit the
cover to the battery compartment (the spring faces towards the batte-
ry) and secure it with the two screws. The clock will now start to run
again. Then use the white adjusting wheel on the housing of the quartz
mechanism in order to set the correct time.
Please ensure that all used and defective batteries are properly dis-
posed of in an environmentally friendly manner.

17
7.3 Wall Mounting
An integral metal bracket located on the rear of the clock enables the
Ex-Time 40 / Ex-Time 50 to be suitably mounted on an appropriate
wall. The fixing of the unit must be secure at all times and precautiona-
ry measures must be taken to prevent the Ex-Time 40 / 50 from falling
into an area classified as zone 0.
7.4 Time Setting
The white adjusting wheel on the quartz mechanism is used to make
any necessary time adjustments.
8. Repairs
Repair work is subject to the nationally valid regulations and directives.
We therefore recommend that such work be performed by ecom
instruments GmbH, Germany, as all repairs must be examined to ensu-
re functional safety.
9. Disposal
Old electrical devices as well as „historical“ old electrical devices from
ecom instruments GmbH are supplied for disposal at our expense and
disposed of free of charge in accordance with European Directive
2002/96/EC and the German electrical law of 16/03/2005. The costs asso-
ciated with returning devices to ecom instruments GmbH are to be borne
by the sender.
10. Cleaning, Maintenance and Storage
- The entire back face of the unit must only be cleaned with a damp
cloth
- Do not use solvents or abrasive cleaning agents to clean the unit.
- The batteries should be taken out of the unit if it is to be out of use
for a length of time.
- The storage temperature should be within the permitted range of
0°C to +50°C.
